Roger T. Allen (born 5 May 1952) is a former territorial level politician from Northwest Territories, Canada.
Allen was first elected to the Northwest Territories Legislature in the 1999 Northwest Territories general election. He defeated future Commissioner Glenna Hansen to win the new Inuvik Twin Lakes electoral district. Allen was re-elected in the 2003 Northwest Territories general election defeating three other candidates with 55% of the vote.
Allen became mired in a scandal after he was found to be living in a residence outside of the Northwest Territories in Grimshaw, Alberta. He swore an affidavit that he lived in a residence just outside Inuvik, Northwest Territories to gain access to the Capital Housing Allowance granting him $25,000 a year for residence in Yellowknife. Allen was forced to appear before a board of inquiry and forced to return $10,000 retroactive to April 1, 2004.
He resigned his seat on October 12, 2004 citing family and personal issues as the reason for stepping down.
